refocusing optics in chamber

i got a question from livermore, if refocusing optics would fit into the zeppelin chamber. in the upper left corner, my problem can be seen.

130mm is the distance for the livermore experiment top flange-interaction region.
100mm is the distance interaction region-beamline port.
the beamline port (1inch: 35mm) is as far out as possible on the 16inch: 360mm chamber flange. nevertheless i lack about 10mm for the beamline port to reach up to the interaction region.

the question is if we could rebuild the livermore experiment, so that we can support it from the support rails instead. then we have no problem fitting both the refocusing optics and the livermore experiment into the chamber.
